Abstract: A piezoelectric acoustic device comprises a case and a piezoelectric element which is accommodated in the case and has an inner peripheral surface thereof supported by an inner peripheral surface of the case at a middle portion thereof. A plurality of projections are provided on an inner peripheral surface of the case and spaced circumferentially along the inner peripheral surface of the case for supporting the peripheral portion of the piezoelectric element. A gap between the peripheral portion of the piezoelectric element and the inner peripheral surface of the case is closed by an elastic adhesive. A plurality of projections provided on and spaced circumferentially along the inner peripheral surface of the case contact the periphery of the piezoelectric element at the tips thereof, which restricts a radial movement of the piezoelectric element relative to the case. The piezoelectric acoustic device that is small-sized and is provided with the piezoelectric element having a small diameter can obtain oscillating frequency equivalent to that of a piezoelectric acoustic device provided with a piezoelectric element having a relatively large diameter.

Abstract: An airbag cushion assembly including an airbag cushion, a cushion strap and a horn switch pocket for use with a driver side airbag module. The horn switch pocket is for mounting a horn switch assembly and is secured to a tether of the cushion strap. The cushion strap retains the airbag cushion in a deflated, folded position prior to mounting the airbag cushion assembly within an airbag module and prior to inflation of the airbag cushion. The horn switch pocket is positioned on the tether so as to be tightly located between the tether and a horn activation face of an airbag module cover of the airbag module. The horn switch pocket can be made from the same material as the tether and the airbag cushion, and the horn switch pocket is sewn to the tether. According to one variation of the present invention, an airbag cushion assembly is provided having an airbag cushion and a horn pocket sewn directly to the airbag cushion.

Granted: 2006-04-04
Abstract: An array for projecting thermal images and a method of making same. The array of the present invention combines a two-tier architecture created with special processing whereby each pixel member (12) resides on an elevated platform directly over discrete pixel control electronics (14) and electrically conducting traces couple a plurality of pixels so that they can be controlled to project thermal images at equal to or faster than video frame rates. Microlens assemblies coupled to each discrete pixel improves the thermal efficiency of the array for certain applications. In the method of fabrication, a semiconductor microbridge-type structure is obtained with the use of sacrificial layer under deposited pixel members in a compact array so that the pixel electronics reside beneath their associated pixel and the array electronics inhabit the same chip as the array thereby improving fill factor and time constant of the resulting array.

Abstract: An avionic system (102) in which engine thrust rating data is transmitted from electronic engine controllers (108a and 108b) to flight management computer/thrust management computers (120a and 120b) via digital data buses (110a, 110c, and 114) is disclosed. The flight management computer/thrust management computers (120a and 120b) select the proper data set for the specified engine thrust rating upon power-up. If the thrust rating changes, the flight management computer/thrust management computers (120a and 120b) select a new data set corresponding to the new thrust rating as received over the digital data bus (110a, 110c, and 114). This is accomplished without the need to change aircraft wiring. The flight management computer/thrust management computers (120a and 120b) store the thrust rating in nonvolatile memory (126), allowing the flight management computer/thrust management computers (120a and 120b) to use the stored value to initialize relevant settings according to current engine thrust rating.

Abstract: A conditional autodialer coupled to a telephone line is adapted to selectively automatically dial a predetermined telephone number, after a predetermined delay period following the appearance of an on-hook to off-hook transition on the telephone line. The autodialer includes an off-hook detector, a touch tone detector, a memory for storing the predetermined number, a dialer and a controller (such as a microprocessor) coupled to receive signals from the off-hook detector and touch tone detector, to communicate with the memory and to provide command signals to the dialer. In operation, the controller responds to an off-hook condition by starting the delay period. If the delay period successfully times out, the controller reads the predetermined number from memory and enables the dialer to dial the number onto the telephone line. However, if, during the delay period, the presence of a DTMF digit or an incoming call is sensed, dialing the predetermined number onto the line is prevented.  Preferably, both the predetermined number and the length of the predetermined delay period are programmable from the telephone set. The conditional autodialer may be embodied in a stand-alone unit or integrated with an individual telephone set.

Abstract: Cette invention concerne un procédé faisant appel à un matériau tubulaire (200) afin de remplacer une valvule cardiaque (118, 120, 162) lors d'une opération de chirurgie cardiaque. Afin de créer une valvule atrio-ventriculaire (120, 160) mitrale ou tricuspide de remplacement, l'entrée du tube est suturée à un anneau (212, 162) de valvule dont on a enlevé les valves originelles, tandis que la sortie du tube est suturée aux muscles papillaires (126, 128, 170) dans le ventricule (112, 152). Afin de créer une valvule aortique ou pulmonaire (118) en forme de demi-lune, l'entrée du tube est suturée à un anneau dont on a enlevé les valves originelles et le tube est soit fixé en trois points distalement à l'intérieur de l'artère, soit suturé longitudinalement le long de trois lignes, ce système permettant aux volets de tissu situés entre les trois points de fixation au niveau de la sortie de la valvule de fonctionner comme des valves mobiles. Ces procédés permettent de générer des modes de débit qui imitent avec précision ceux de valvules originelles. Le matériau tubulaire (200) préféré consiste en un tissu prélevé sous la muqueuse de l'intestin grêle, lequel tissu peut être prélevé chez le patient qui subit l'opération du coeur de manière à limiter les risques d'antigénicité. Des tissus intestinaux d'animaux ou de cadavres peuvent également être utilisés du moment qu'ils ont été traités de manière adéquate, de même qu'un matériau tubulaire synthétique et biocompatible. Cette invention concerne également un segment de tissu intestinal traité de manière adéquate, ou encore un segment tubulaire synthétique (500), lesquels peuvent être utilisés en transplantation afin de remplacer une valvule cardiaque, et sont scellés dans une emballage stérile (510).

Abstract: De façon générale, l'invention concerne un système de filtration à recirculation destiné à un spectromètre de mobilité ionique (IMS) portable. Un premier mode de réalisation préféré dudit système comprend une pompe reliée par un ensemble de filtres et de capteurs de débit à un capteur IMS. Le flux de sortie du capteur IMS est nettoyé par les filtres et remis en circulation par la pompe, qui le renvoie dans le capteur IMS en tant que flux de courant fluidique support. Une partie du flux de sortie du capteur égale à la quantité de flux qui y a été introduite est évacuée du système de filtration, ce qui permet de maintenir un débit total constant dans l'ensemble du système lorsque l'échantillon est prélevé. Un second mode de réalisation préféré comporte un système de filtration à recirculation portable qui permet de mesurer une concentration inconnue d'une substance contaminante ionisable sélectionnée présente, telle que du benzène, dans laquelle d'autres substances peuvent coexister, et qui emploie un dispositif permettant d'introduire une concentration contrôlée du contaminant ionisable sélectionné dans un capteur d'IMS. La concentration inconnue est calculée par la méthode d'addition standard. Le second mode de réalisation préféré peut également être utilisé pour étalonner le capteur IMS en déterminant quelles sont les structures d'ionogramme obtenues en présence d'un analyte particulier dans le flux d'échantillonnage. Un troisième mode de réalisation préféré est un système de filtration à recirculation destiné à un spectromètre de mobilité ionique portable pour des applications de chromatographie en phase gazeuse. Ledit système comprend une pompe et un ensemble de filtres et de capteurs de débit reliés à un capteur IMS comportant à son entrée une colonne de chromatographie gazeuse.
